tango v l'ln: Truck-section lornred by the rails ends of the bell-crank and to a sliding plate G". An upright lever G pivoted intermediate its ends to any suitable bracket, is pivotally connected at its lower end to the plate G. A second car in advancing in the tisple will strike and throw the tripping-lever withdrawing the bell-cranks G from in advance of the wheels of the receding car, and it will be struck and force from the tip le, provided the track-section is substantial y horizontal and the grade is omitted, as may be the case. A spring G is employed to throw the parts to their normal position after the car passes the tripping-lever G After the car has assed the tripping-lever G and the spring has again set the bellcranks the carstrikes a wei hted rod H, pivoted between its end and held by its lower weighted end in a normally vertical position. When the car has passed this rod or bar H, its front wheels ar e caught and locked by the bell-cranks G, and'the bar H rises on the rear side of the oar-axle and prevents a recoil movement of the car, as the sto H prevents rearward movement of the bar Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is

1. The combination with a platform, a shaft carried horizontally thereby, a brakewheel carried by the shaft, a brake-band, a lever adapted to re ulate the pressure of the band u on the braie-wheel, a track-section carried y the shaft, the outer rail of the track being .a greater distance from the shaft than the inner rail, and counterwei hts depending from the shaft and adapted tOilOld the tracksection in normally a horizontal lane.

2.'The combination with a ti ting tracksection, of bell-crank levers pivotally carried by said section and normally projectin across the track-rails, a slidable plate carrie by the section, a tripping-lever plvotall f connected to the plate, a spring adapted to re turn the plate to its normal position, and rods pivotally connected at one end to the inner ends, respectively, of the bell-crank levers, and at their opposite ends to the late.
